Since I started using collectd plugin, the R7800 CPU doesn't scale frequency anymore

Hi, I don't know if it's normal because collectd uses more system resources, but since I started to collect more data, and I send it to my InfluxDB, the CPU of the R7800 runs almost always at 1.73ghz.

I don't understand if it's an issue with the graph, or it's true, because on the main graph the frequency is at 1.7ghz, but on the detailed graph seems to be at 600Mhz almost all the time. Also the system load in the last days is normal like the before. So I don't understand what's going on.

To be honest I don't care much about the CPU scaling, it can remain also at the maximum speed, but I just want to understand what's happening.

Thanks!
